INSTALLATION
(SEE FIGURE 1)
1. Pump installation site should provide easy
access for routine maintenance and where
possible to protect the pump from the
elements and from leaks or drips from nearby
process equipment.
2. Bolt the pump motor down firmly to mounting
surface. Provide for air movement over electric
motor.
3. Looking at the pump from the magnetic drive
end, the suction port is to the right when the
pump drive shaft rotates clockwise and is
located below the ports. Reversing drive shaft
rotation reverses flow and thus suction and
discharge ports. Verify proper motor rotation
before final piping.
4. To check system operation, installation
of vacuum/pressure gauges in the
suction and discharge lines is
recommended.
5. Keep suction lines short and straight to
minimize friction loss to the pump.
Make sure that the pump will not run
dry. Flooded suction or gravity feed of
fluid to pump inlet is generally preferred.
6. Use only full-bore ball valves or gate
valves in the suction piping. If suction
strainers are used size them to minimize
pressure drop and select those of a type
that are easily cleaned.
7. Arrange all suction piping and fittings to
prevent formation of air pockets. Make
sure all joints are air tight.
8. Flush and blow out all suction lines prior
to mating up to pump. Use nipples and
unions, for ease of maintenance.
